You're probably low on refrigerant. If so, it's easy enough to replace, but you'll want to make sure that the root cause isn't a big leak. A small leak at the compressor (that takes years to notice) is normal.

You don't hear about it as much any more. Perhaps the supplier fixed whatever was wrong with the part.

Have you been seeing other weird characters on the HVAC console? If it starts doing that, the console unit needs replacing. That happened to me a few years ago and the parts guy at the dealer said they'd been changing them right and left under warranty.

I had the same problem last summer, my fix was to change the ambient temp. sensor because my outside temp. on the console would read way higher than it was outside ,one day it was 88 outside my temp reading was 110 when it would do that it would blow hot air. I changed that and t-stat witch I already put in the 160 but changed it again. I'm not a fan of dexcool antifreeze there has been a lot of issues for GM over its use, I never heard if it effects the newer Vettes or not. I hav'nt had an issue with it since doing that.
